I have a Date custom field and want to set it's default value to the current date.  As it is now, date custom fields only support a static date.  I've looked into the CRM/Contact/Form/CustomData.tpl template to see if I can set a default date there, but it looks like it's getting the data using AJAX and I don't know where to hook in to the AJAX call (is there a way?).

Thanks for any help.

Sweet!  That works.  The next problem is that this custom data group allows multiple records.  I figured out that the _1 in the id represents the record number, so I can just create defaults for all of the expected record numbers (in the example below, it allows for 100 new records), ie:

for ($i = 1; $i < 100; $i++) {
$defaults['custom_12_-' . $i] = $defaultDate; // NAFY Client Demographics / Date Recorded
}

How do I figure out the record number of the last record so I can create defaults starting from that record number?  In other words, what $i should start with.  This isn't a big deal since presumably it won't hurt to set defaults for existing records.

Thanks!

When the custom data is in edit mode the records get populated with AJAX, so they're not in the $form->_elements array.  In view-only mode they are in the $form->_elements array, so I guess I could save them off and then refer to them later.  Or I could retrieve them using AJAX from PHP?

Do you have any other suggestions?

Thanks lobo.

If it helps. Function which process defaults in QuickForm package "setDefaults" do it twice.

print_r($defaultValues) shows that function was called twice. First time w/o custom fileds and second - with them.  It set some trigger here
           $this->_defaultValues = HTML_QuickForm::arrayMerge($this->_defaultValues, $defaultValues);
            print_r($this->_defaultValues);
            foreach (array_keys($this->_elements) as $key) {
                $this->_elements[$key]->onQuickFormEvent('updateValue', null, $this);
            }

Logically that first time was civicrm call, second - my call.

in most pages custom fields are retrieved via an AJAX call to the same page. hence u see the code being called twice

In that case print_r result must be appended to <div id="custom_values"> but I see two arrays in the top of page before html generated by Smarty. So can it be that only first call affects default custom fields? Code in example fails on clear Civi 3.0.2 (3.0.3 same situation) with only one custom field. I think it is some bug.

Hi,

I have a somehow related problem, the name of the custom fields seem to change between contacts based on ?

it is sometimes,
custom_1_-1
custom_1_3
custom_1_6

Not sure why it changes between contact. What is the reliable way to modify a custom field in a hook ?

i dont understand what u mean exactly. i've been using a fair amount of hooks in 2.2, and will upgrade that module to 3.1 soon

in the meantime, u can help by tracing and figuring out the issue with the code. contact us on IRC if u need help getting started

Sorry for my bad English

Part of issue is lack of attention.

My issue was there:

if( !empty($_GET['template_id']) && $_GET['template_id']>0)

In Ajax GET not presented template_id parameter (provided event subtype only), so I unable to set custom fields defaults according to event template settings even with hook. Maybe it isn't a bug. But a big mistake I think. Issue may be resolved by hack of "customData.tpl" and using setDefaults in hook_buildForm. E.G.:

customData.tpl
{literal}
<script type="text/javascript">

function buildCustomData( type, subType, subName, cgCount, groupID, isMultiple )
{
var dataUrl = {/literal}"{crmURL p=$urlPath h=0 q='snippet=4&type='}"{literal} + type;

if ( subType ) {
dataUrl = dataUrl + '&subType=' + subType;
}

if ( subName ) {
dataUrl = dataUrl + '&subName=' + subName;
cj('#customData' + subName ).show();
} else {
cj('#customData').show();
}

{/literal}
{if $urlPathVar}
dataUrl = dataUrl + '&' + '{$urlPathVar}'
{/if}
{if $groupID}
dataUrl = dataUrl + '&groupID=' + '{$groupID}'
{/if}
{if $qfKey}
dataUrl = dataUrl + '&qfKey=' + '{$qfKey}'
{/if}
{if $entityID}
dataUrl = dataUrl + '&entityID=' + '{$entityID}'
{/if}
{literal}

if ( !cgCount ) {
cgCount = 1;
var prevCount = 1;
} else if ( cgCount >= 1 ) {
var prevCount = cgCount;
cgCount++;
}

dataUrl = dataUrl + '&cgcount=' + cgCount;
        
         /*hack*/
var reg = /&template_id=[\d]+/i; //get template_id
n = reg.exec( document.location );
if(n[0] != ''){
dataUrl = dataUrl + n[0];
}
         /*hack*/

if ( isMultiple ) {
var fname = '#custom_group_' + groupID + '_' + prevCount;
cj("#add-more-link-"+prevCount).hide();
} else {
if ( subName && subName != 'null' ) {
var fname = '#customData' + subName ;
} else {
var fname = '#customData';
}
}

var response = cj.ajax({
url: dataUrl,
async: false
}).responseText;

cj( fname ).html( response );
}

</script>
{/literal}


hook_buildForm
function setCustomFieldsDefaultKeys($_fields=array()){

//set all default values like in event template
foreach($_fields as $key => $val){

$nkey = preg_replace('/(custom_[\d]+_)[\d]+(_id)?/i', '\1-1\2', $key);
$_defaults[$nkey] = $val;
}

return $_defaults;
}

///Hooks implementation

function mymodule_civicrm_buildForm( $formName, &$form )
{

civicrm_initialize();
switch($formName){
case 'CRM_Event_Form_ManageEvent_EventInfo':

require_once 'api/v2/Event.php';

//defaults from template
if( !empty($_GET['template_id']) && $_GET['template_id']>0 ){

$params = array( 'id'=> $_GET['template_id'] );
$result = civicrm_event_get( $params );
$defaults = setCustomFieldsDefaultKeys($result);

$form->setDefaults( $defaults );
}

default:
break;
}
}

UPD: In CiviCRM 3.1.2 this issue was fixed. Thanks for your hard work
